Tk_GetJoinStyle(3) Tk Library Procedures Tk_GetJoinStyle(3)
NAME
Tk_GetJoinStyle, Tk_NameOfJoinStyle - translate between strings and
join styles
SYNOPSIS
#include <tk.h>
int
Tk_GetJoinStyle(interp, string, joinPtr)
const char *
Tk_NameOfJoinStyle(join)
ARGUMENTS
Interpreter to use for error reporting. String containing name of join
style: one of or Pointer to location in which to store X join style
corresponding to string. Join style: one of JoinBevel, JoinMiter,
JoinRound.
DESCRIPTION
Tk_GetJoinStyle places in *joinPtr the X join style corresponding to
string, which will be one of JoinBevel, JoinMiter, or JoinRound. Join
styles are typically used in X graphics contexts to indicate how adja-
cent line segments should be joined together. See the X documentation
for information on what each style implies.
Under normal circumstances the return value is TCL_OK and interp is
unused. If string does not contain a valid join style or an abbrevia-
tion of one of these names, then an error message is stored in
interp->result, TCL_ERROR is returned, and *joinPtr is unmodified.
Tk_NameOfJoinStyle is the logical inverse of Tk_GetJoinStyle. Given a
join style such as JoinBevel it returns a statically-allocated string
corresponding to join. If join is not a legal join style, then is
returned.
KEYWORDS
